System for decomposing events from managed infrastructures with prediction of a networks topology

ABSTRACT

An event clustering system is provided that in response to a time series infers a network topology. Matrices W and H are estimated as a local minimum. For each pair of nodes: (i) a computation of the convolution is made; a number of peaks within the convolution is a function of a delay; and a comparison is made to an average behavior of a pair of nodes that emits the same number of alerts. Alerts are only spread to adjacent nodes, alerts are caused by dysfunctional nodes that do not emit alerts, and a true topology coincides with the end of the recording.

Description of the Related Art

The World Wide Web is increasingly becoming a more important and more frequently used form of communication between people. The primary form of web-based communication is electronic mail. Other forms of communication are also used, however, such as news groups, discussion groups, bulletin boards, voice-over IP, and so on. Because of the vast amount of information that is available on the web, it can be difficult for a person to locate information that may be of interest. For example, a person who receives hundreds of electronic mail messages/events from infrastructure a day may find it impractical to take the time to store the messages/events from infrastructure in folders of the appropriate topic. As a result, it may be difficult for the person to later find and retrieve all messages/events from infrastructure related to the same topic. A similar situation arises when a person tries to locate news groups or discussion groups of interest. Because there may be no effective indexing of these groups, it can be difficult for the person to find groups related to the topic of interest.

Some attempts have been made to help the retrieval of information of interest by creating web directories that provide a hierarchical organization of web-based information. The process of creating the directories and deciding into which directory a particular piece of information (e.g., a news group) should go is typically not automated. Without an automated approach it is impractical to handle the massive amounts of web-based information that are being generated on a daily basis. Moreover, because a person may not be fully aware of the entire web directory hierarchy or may not fully understand the semantics of information, the person may place the information in a directory that is not the most appropriate, making later retrieval difficult. It would be desirable to have an automated technique that would help organize such information.

The advent of global communications networks such as the Internet has provided alternative forms of communicating worldwide. Additionally, it has increased the speed at which communications can be sent and received. Not only can written or verbal messages/events from infrastructure be passed through the Internet, but documents, sound recordings, movies, and pictures can be transmitted by way of the Internet as well. As can be imagined, inboxes are being inundated with countless items. The large volume can more than difficult to manage and/or organize for most users.

In particular, a few of the more common activities that a user performs with respect to email, for example, are: sorting of new messages/events from infrastructure, task management of using messages/events from infrastructure that can serve as reminders, and retrieval of past messages/events from infrastructure. Retrieval of recent messages/events from infrastructure can be more common than older messages/events from infrastructure. Traditional systems employed today support at least some aspect of these three activities using folders such as an inbox, task-oriented folders, and user-created folders, respectively. However, this as well as other existing approaches present several problems. The folders make stark divisions between the three activities which are not conducive or coincident with user behavior, in general. For example, tasks are not visible to the user, or rather are “out of sight, out of mind”, and thus can be easily, if not frequently, neglected, overlooked, or forgotten. In addition, in many current systems any given message can only be in one folder at a time. Hence, the particular message cannot serve multiple activities at once. Other current systems have attempted to ease these problems; however, they fall short as well for similar reasons.

A user can communicate using one or more different messaging techniques known in the art: email, instant messaging, social network messaging, cellular phone messages/events from infrastructure, etc. Typically, the user can accumulate a large collection of messages/events from infrastructure using one or more of these different messaging techniques. This user collection of messages/events from infrastructure can be presented as a large collection of messages/events from infrastructure with limited options of grouping or clustering the messages/events from infrastructure.

One way of grouping messages/events from infrastructure is to group multiple emails into an email thread. An email thread is a collection of emails that are related based on the subjects of the emails. For example, one user sends an email to one or more users based on a given subject. Another user replies to that email and a computer would mark those two emails as belonging to a thread. Another way for grouping messages/events from infrastructure is put the messages/events from infrastructure into folders. This can be done manually by the user or can be done automatically by the user setting up rules for message processing.

Document clustering and classification techniques can provide an overview or identify a set of documents based upon certain criteria, which amplifies or detects certain patterns within its content. In some applications these techniques lead to filtering unwanted email and in other applications they lead to effective search and storage strategies. An identification strategy may for example divide documents into clusters so that the documents in a cluster are similar to one another and are less similar to documents in other clusters, based on a similarity measurement. One refers to the process of clustering and classification as labeling. In demanding applications labeling can greatly improve the efficiency of an enterprise, especially for storage and retrieval applications, provided that it is stable, fast, efficient, and accurate.

Users of information technology must effectively deal with countless unwanted emails, unwanted text messages/events from infrastructure and crippling new viruses and worms every day. This largely unnecessarily high volume of network traffic decreases worker productivity and slows down important network applications. One of the most serious problems in today's digital economy has to do with the increasing volume of spam. As such, recipients of email as well as the service providers need effective solutions to reduce its proliferation on the World Wide Web. However, as spam detection becomes more sophisticated, spammers invent new methods to circumvent detection. For example, one prior art methodology provides a centralized database for maintaining signatures of documents having identified attributes against which emails are compared, however, spammers now modify the content of their email either slightly or randomly such that the message itself may be intelligible, but it evades detection under various anti-spam filtering techniques currently employed.

At one time, at least 30 open relays dominated the world, bursting messages/events from infrastructure at different rates and different levels of structural variation. Because certain types of email mutate or evolve, as exemplified by spam, spam-filtering detection algorithms must constantly adjust to be effective. In the case of spam email, for example, the very nature of the spam corpus undergoes regime changes. Therefore, clustering optimality depends heavily on the nature of the data corpus and the changes it undergoes.

Decomposing a traffic matrix has proven to be challenging. In one method, a matrix factorization system is used to extract application dependencies in an enterprise network, a cloud-based data center, and other like data centers, using a temporal global application traffic graph dynamically constructed over time and spatial local traffic observed at each server of the data center. The data center includes a plurality of servers running a plurality of different applications, such as e-commerce and content delivery. Each of the applications has a number of components such as a, web server, application server and database server, in the application's dependency path, where one or more of the components are shared with one or more of the other applications.

Because such data centers typically host a large number of multi-tier applications, the applications requests are overlapped, both in the spatial and temporal domains, making it very difficult for conventional pair wise statistical correlation techniques to correctly extract these interleaved but independent applications. A matrix-based representation of application traffic is used which captures both system snapshots and their historical evolution. The system and method decomposes a matrix representation of application graphs into small sub-graphs, each representing a single application.

The number of applications is usually unknown a priori due to interleaving and overlapping application requests, which further imposes a challenge to discovery of the individual application sub-graphs. In one prior method and system, the number of applications is determined using low rank matrix estimation either with singular value decomposition or power factorization based solvers, under complete and incomplete traffic data scenarios, with theoretical bound guarantee.

Traffic tapping from switches is limited by the capability of switches as well as the monitoring hosts. A switch typically can mirror only a few ports at the same time. In addition, monitoring data collected over multiple switches, each with multiple ports may result in high-volume aggregate network traffic and potentially packet loss. Both cases lead to significant loss in the monitoring data.

One system and method to overcome this problem utilizes historical data to provide redundancy and employs power factorization based techniques to provide resilience to data loss and estimation errors. In one system and method, a distributed network monitors and centralizes data processing to determine application dependency paths in a data center.

The majority of current service management solutions are rule based. The concept behind rule-based systems is that you start with the system you are monitoring, analyze and model it, turning it into a series of business logic rules that respond to events as they occur. For example, in response to some logged text, you apply logic that turns the text into a database record to which you apply more logic that turns it into an alert, before applying again more logic to connect the alert to a trouble ticket.

There is a need to provide systems in response to a time series that infers a network topology.

For purposes of the present invention, the Internet, extranets and intranets collectively are referred to as (“Network Systems”).

For purposes of the present invention, the term “managed infrastructure” means, information technology, the physical hardware used to interconnect computers and users, transmission media, including telephone lines, cable television lines, and satellites and antennas, and also the routers, aggregators, repeaters, computers, network devices, applications, and other devices that control transmission paths, software used to send, receive, and manage the signals that are transmitted, and everything, both hardware and software, that supports the flow and processing of information.

As used herein, “event message” or “event” is defined as a change in state. An event is anything that happens, or is contemplated as happening in message form or event form relating to managed infrastructure. An event can include a time stamp, and a name for the entity changing state.

Referring to FIG. 1, an event clustering system 10 (hereafter “system 10”) is provided for clustering events received from a managed infrastructure 14.

In one embodiment system 10 includes an extraction engine 12 in communication with a managed infrastructure 12. Extraction engine 12 in operation receives messages from the managed infrastructure 14, produces events that relate to the managed infrastructure 14 and converts the events into words and subsets used to group the events into clusters that relate to failures or errors in the managed infrastructure 14. The managed infrastructure 14 includes physical hardware and supports the flow and processing of information.

As a non-limiting example, managed infrastructure system 14 hardware includes but is not limited to: computers, network devices, appliances, mobile devices, applications, connections of any of the preceding, text or numerical values from which those text or numerical values indicate a state of any hardware or software component of the managed infrastructure 14, and the like.

Managed infrastructure 14 generates data that includes attributes. As a non-limiting example, the data is selected from at least one of, time, source a description of the event, textural or numerical values indicating a state of the managed infrastructure 14.

In one embodiment system 10 makes physical changes in the managed infrastructure including but not limited to: managed infrastructure hardware changes that create physical and virtual links between the managed infrastructure and system 10 server, as well as change to links from the server to system 10 high speed storage.

In one embodiment extraction engine 12 communicates with managed infrastructure 14 across an IP network 15 at high speed and with low latency. As a non-limiting example high speed connection is in the gigabits and low latency is in the microseconds. As a non-limiting example high speed is at least 1 gigabit, and low latency is at least 10 microseconds

In one embodiment, illustrated in FIG. 2, extraction engine 12 includes a central processor 16, a main memory 18, an input/output controller 20, an interface 22 that can be include an optional keyboard, a display 24, and a storage device 26. Storage device 26 can communicate through a system bus 28 or similar architecture.

Referring to Figure's 3(a) and (b) in one embodiment a software system 30 directs the operation of the extraction engine 12. Software system 30, which can be stored in memory 18, can include an operating system 32 and a shell or interface 34. A user can interact with the software system 30 via interface 22.

Application software 36 can be transferred from storage device 26 which can be via software system 30 into memory 18 for execution by extraction engine 12.

In one embodiment extraction engine 12 receives user commands and data through interface 22. These inputs can be acted on by extraction engine 12 with instructions from operating system 32 and/or application system 34. In one embodiment operating system 32 and/or application system 34 are included in operating software system 30.

The extraction engine 12 breaks event messages 40 into subsets of messages that relate to failures or errors in managed infrastructure 14. In one embodiment the extraction engine 12 breaks events 40 into subsets of messages relative to failure or errors in an managed infrastructure 14 via a message input mechanism, including but not limited to, an input/output controller 20, with or without operating system 32 and/or application system 34, that parses machine elements 38 from managed infrastructure 14 in memory 18. As a non-limiting example machine elements are machine messages.

This can be achieved using operating system 32 and/or application system 34 as well as application software from storage device 26.

In one embodiment the extraction engine 12 receives managed infrastructure data and produces events 40 as well as populates an entropy database 42, illustrated in FIG. 4, with a dictionary of event entropy that can be included in entropy database 42. This can be achieved with a token counter 58 as illustrated in FIG. 5.

In one embodiment, entropy database 42 is generated with the word and subtexts. As a non-limiting example the entropy database 42 is generated using Shannon Entropy, −ln(1/NGen) and normalizes the words and subtexts as follows:

−ΣP (t) log P(t)

where, P(t=probability of each item is selected randomly from an entire dataset.

In one embodiment entropy database 42 normalizes events across data, datasets, from the managed infrastructure 14. As a non-limiting example, normalized entropy for events is mapped from a common, 0.0 and a non-common, 1.0, as discussed hereafter. Entropy is assigned to the alerts. The entropy for each event is retrieved from an entropy dictionary, as it enters the system 10. This can be done continuously in parallel with other operation of the extraction engine 12 or run non-continuously.

In one embodiment entropy database 42 is generated with the word and subtexts. A network includes a plurality of nodes, which as a non-limiting example can be nodes 1-6. A non-directed graph is used to calculate graph entropy for each node in the graph.

The non-directed graph calculates graph entropy for each node in the graph as follows: (i) the source data is used to calculate the graph data; (ii) the non-directed graph is used to calculate the number of links and the clustering coefficient of the node; (iii) the number of links and clustering coefficient of the node together with the total number of links in the graph is then used to calculate an entropy value for each node.

In one embodiment, entropy normalizes events 40 across data, datasets, from the managed infrastructure 14. As a non-limiting example, normalized entropy for events 40 is mapped from a common, 0.0 and a non-common, 1.0, as discussed hereafter. Entropy is assigned to the alerts 20. The entropy for each event is retrieved from entropy database 42 as it enters the system 10. This can be done continuously in parallel with other operation of the extraction engine 12 or run non-continuously.

An N event value is attached to every event of the entropy graph of the source node. Entropy values are used as a cutoff to ignore events 40 from unimportant nodes to classify events 40.

As a non-limiting example the entropy database 42 is generated using Shannon Entropy, −ln(1/NGen) and normalizes the words and subtexts as follows:

−ΣP.(t) log P(t)

where, P(t,)=probability of each item is selected randomly from an entire dataset.

In one embodiment graph entropy is used as a classification mechanism for elements for a network.

As recited above, system 10 is provided for clustering events 40 received from managed infrastructure 14. In this embodiment graph entropy is utilized for event clustering.

The graph entropy functions of the paths can be rewritten as the following equation: H(G)=Σm,n=1.quadrature.U.quadrature.P(um un . . . )log(1/P(um un . . . )),m.notequal to n

where P(u_(m)u_(n)) can be rewritten as the following equation by combining the aforementioned equation P(u_(m)u_(n))=A(u_(m))y(u_(m), u_(n))A(u_(n))

As a non-limiting example an inference is created from a distribution of the clustering events 40 received from managed infrastructure 14 relative to the nodes, and using graph, with the distribution entropy measured.

As a non-limiting example the entropy of the frequency distribution of connections of the nodes can be used.

As a non-limiting example the events 40 less significant can be can be −log(p), and with a low probability represented as (p˜0) and more significant events 40 are classified as very probable (p˜1). The average is the sum over all nodes i of

−p_i*log(p_i)

or:

average(−log(p_i))

where p_i is the number of connections of the i-th node divided by the total number of connections. The entropy is the uncertainty of the nodes relative to the clustering events 40 received from managed infrastructure 14.

As a non-limiting example this can be achieved by using an IP protocol stack 46 that communicates with managed infrastructure network protocols 48. The managed infrastructure network protocols 48 can be in communication with application software 36. In one embodiment IP protocol stack 46 can be executed using one or more of

In one embodiment embedded agents 50 in hardware components 52, which can be included in extraction engine 12, gather attributes 54 to a managed infrastructure 14 system health to generate data that includes attributes 54. As non-limiting examples hardware components 52 include but are not limited to: computing devices, network switches and devices, storage devices, environmental sensors, power sensors and the like. In one embodiment hardware components 52 can be included in operating system 32 and/or application system 34 and the like.

In one embodiment interface 22, which can include display 24, serves to display results and the user can supply additional inputs or terminate a given session.

In one embodiment operating system 32 can switch between a manual mode and an automatic mode based on constant monitoring. In one embodiment application system 34 can include instructions such as the operations described herein, including but not limited to extracting text components from event 40 messages and convert them into words and subtexts.

In one embodiment operating system 32 and/or application system 34 then reformats data from the event 40 messages to create reformatted data. In one embodiment, the reformatted data is received at bus 28.

In one embodiment extraction engine 12 has a library 56 stored in memory 22.

As a non-limiting example library 56, which can be part of database 42, recognizes sub-categories of messages. As a non-limiting example this is used to reformat data from the event 40 messages to create reformatted data.

The subsets and/or sub-categories of messages can be grouped into clusters. In one embodiment the grouping into clusters is achieved using operating system 32 and/or application system 34.

Referring to FIG. 6 one or more signalizer engines 110 (hereafter “signalizer engine 110”) can include one or more of an NMF engines 224, a k-means clustering engine 226 and a topology proximity engine 228. The signalizer engine 110 determines one or more common steps from events 40 and produces clusters relating to events 40. Each signalizer engine 110 includes a processor and an arithmetic logic unit “ALU”. Examples of suitable ALUs are found in EP 0171190 and EP 0271255, fully incorporated herein by reference. In one embodiment, signalizer engine 110 determines one or more steps from events 40 and produces clusters relating to the alerts and or events 40.

The signalizer engine 110 determines one or more common characteristics of events 40 and produces clusters of events 40 relating to failure or errors in the managed infrastructure 14. Membership in a cluster indicates a common factor of the events 40 that is a failure or an actionable problem in the physical hardware managed infrastructure 14 directed to supporting the flow and processing of information.

The topology proximity engine 228 uses a source address for each event 40 and a graph topology of the managed infrastructure 14 that represents node to node connectivity, of the topology proximity engine 228, to assign a graph coordinate to the event with an optional subset of attributes being extracted for each event and turned into a vector. The topology engine 228 inputs a list of devices and a list a connections between components or nodes in the managed infrastructure.

The k-means clustering engine 226 uses the graph coordinates and optionally can use a subset of attributes assigned to each event to generate a cluster in order to bring together events 40 whose characteristics are similar. NMF engine 224 factors a matrix M into A and B, where A is inspected and substantially significant clusters are extracted, and B is used to assign a start and end times for each cluster. An output of clusters is produced. In response to production of the clusters one or more physical changes in one or more managed infrastructure hardware elements is made.

It will be appreciated that signalizer engine 110, NMF engine 224, k-means clustering engine 226 and topology proximity engine 228 can have all or some of the elements similar to those of extraction engine 12 including but not limited to: a central processor, a main memory, an input/output controller, an interface that can be an optional keyboard, a display, a storage device, computer software system, directing operation of relevant engine 224, 226 and 228, a software system, operating system, software transferred from a storage device into memory for execution the associated engine 224, 226 and 228, an input/output controller with or without an operating system, application system, and the like. In one embodiment subsets of messages are grouped into clusters by using a signalizer engine 110, FIG. 6, that has an array of engine components similar or the same as those in extraction engine 12, including but not limited to, computing devices, network switches and devices, storage devices, environmental sensors, power sensors and the like, across a network volatile memory to analyze and create alerts.

In one embodiment a computer software system directs the operation of the signalizer engine 110. Software system, which can be stored in memory, a disk memory and the like, can include an operating system, a shell or interface and an application system.

A user can interact with software system with via the interface. Application software can be transferred from storage device into memory for execution by signalizer engine.

In one embodiment signalizer engine 110 receives user commands and data through an interface. These inputs can be acted by signalizer engine 110 with instructions from operating system and/or application system. In one embodiment operating system and/or application system are included in operating system.

In one embodiment signalizer engine with the array of engine components similar to those of extraction engine 12, groups subsets of messages into clusters.

In one embodiment signalizer engine 110 includes an array of engine components 112 that perform the grouping of message subsets into clusters. In one embodiment the engine components can include the operating system, application system and the like. In one embodiment engine components 112 include but are not limited to: computing devices, network switches and devices, storage devices, environmental sensors, power sensors and the like.

In one embodiment signalizer engine 110 includes a plurality of engines as illustrated in FIG. 6. As non-limiting examples, an NMF engine 224, a k-means clustering engine 226 and a topology proximity engine 228 are provided. Each signalizer engine 110 includes a processor and an arithmetic logic unit “ALU”. Examples of suitable ALUs are found in EP 0171190 and EP 0271255, fully incorporated herein by reference. In one embodiment, signalizer engine 110 determines one or more steps from events 40 and produces clusters relating to the alerts and or events 40.

Signalizer engine 110 determines signalizer common steps to ascertain how many clusters to extract from events 40. Membership in a cluster indicates a common factor, which can be a failure or an actionable problem in the managed infrastructure 14. In one embodiment signalizer engine 110 generates clusters of alerts. In one embodiment, an independent failure count detection engine 229 is used for the production of common steps designated as “k” from events 40. The independent failure count detection engine 229 can use SVD decomposition. The SVD decomposition is a continuation of a determination of signalizer 110 common steps.

K is the number obtained from the common signalizer steps. As a non-limiting example, common signalizer steps are designated as Mij, where i are unique events 40 and are the rows of M, j represents the time buckets in M. A value for Mij equals the number of occurrences of event i in time bucket j. This is the common input to the signalizer engines 110.

In one embodiment topology proximity engine 228 creates a graph coordinate system, FIG. 9. In one embodiment topology proximity engine 228 uses a source address for each event to assign a graph coordinate 230 of a graph 232, with nodes, to the event with an optional subset of attributes being extracted for each event and turned into a vector. The topology proximity engine 228 executes a graph topology and proximity algorithm.

Mik undergoes K-means decomposition, FIG. 7. Each event is a transformed vector, where (Vo is transformed time stamp, Vi, −Vn and so forth are transformed graph coordinates 234) are grouped into k clusters such that d(Vi, V2,) is minimized. In one embodiment, the topology engine 228 inputs a list of devices and a list of hops, where hop is a connection between components or nodes in the managed infrastructure 14.

As a non-limiting example, the graph 232 can be constructed of any number of points or nodes: A, B, C, and D, which relate to the source of an event. The result is a connecting graph 232, FIG. 7.

The topology proximity engine 228 receives the coordinate's mapping, and clusters are generated. V base nodes calculate a minimum hops to every other node which gives coordinate and the graph coordinates 230 are mapped.

In one embodiment, the k-means clustering engine 226 uses the graph coordinates 230 to cluster the events 40 using a k-means algorithm to determine hop proximity of the source of the event.

M,k is processed by the signalizer engine 110. Mab is transformed to Aak

Bkb, where a equals rows, and b equals columns, x defines the normal operation of matrix multiplication. M is the matrix as stated above, and k is as recited above.

The NMF algorithm produces two matrices, A and B, FIG. 8. A represents by cluster (a common failure) and B represents time bucket by cluster (a common failure). In one embodiment, the NMF engine 224 factors the matrix M into A and B, where A are deemed to be significant and are extracted, e.g., clusters deemed significant are extracted. The system 10 looks for significantly high values as compared to statistically significant values in the A and B matrix. If they are not statistically significant, they are dropped. The statistically significant elements of M are used to determine a cluster. As a non-liming example, the determination of significance is based on high signatures in the matrix. As above, those that are not high enough are dropped and not included in the output of clusters which is produced.

Each alert is mapped to a vector, VO-Vn, where Vo is a time stamp t; Vi is an attribute of alert. In one embodiment, attributes of an event are mapped to a vector V.

The vectors are grouped into k clusters using k-means such that d(Vi, V2,) is a minimum in its own cluster.

In one embodiment the grouping is executed also using a standard Euclidian distance. In one embodiment, a weighting of components is supplied. System 10 transforms the alert attributes into a number value that is used as the components of the vector. As a non-limiting example, an alert attribute is a textual value. In one embodiment, similar attributes are mapped to numbers that are also similar or close relative to the graph, with the closeness being dynamic and can be predetermined, changed, modified, set, and the like.

In one embodiment of the matrix, M, columns are slices in time and the rows are unique alerts. A unique alert is received from the deduplication engine 23 which eliminates duplications and creates unique alerts.

In one embodiment, the matrix, M is created with alert/time and a fixed number of common alerts. The matrix M can be dynamic and change in time. The matrix M includes rows that can be unique alerts. The matrix includes columns that are time buckets, and a number of occurrences are plotted.

Evaluated events 40 are either discarded or passed to clusters with alerts are collected into time buckets and mapped in the matrix M. In one embodiment, a bucket width is a parameter that can be an input to the signalizer engine 110.

Outputs from the signalizer engines 110 are received at a compare and merge engine 334. The compare and merge engine 334 communicates with one or more user interfaces 22 in the situation room 336, FIG. 10. The three signalizer algorithms are used with the comparison or merger engine 334 and clusters are published on system 10 for display in the situation room 336.

As a non-limiting example, the bus 28 can be a publication message bus. As a non-limiting example, the bus 28 processes anything that goes from A to B, and from B to A. In one embodiment, a data bus web server is coupled to user interfaces.

As illustrated in FIG. 10, a plurality of link access modules 340 are in communication with the data bus 438 and receive messages/events 40. Events 40 are received by a coordinator 342 that executes clustering of the events 40.

In one embodiment, normalized words and subtexts are mapped to a common, 0.0 and a non-common, 1.0, as illustrated in FIG. 5.

The alerts can be run in parallel with the activities of the system 10. The alerts are passed to the signalizer engine 110, FIG. 6.

In one embodiment, deduplication engine 236, FIG. 11, is used for event messages of data streams received from the client. The deduplication engine 236 eliminates duplicate copies of repeating data. In one embodiment, the deduplication engine 236 reduces a number of bytes in network data transfers that need to be sent.

A computer scripting language script language can be included that alters the events 40 or flow of events 40. As non-limiting examples, the scripting language can be, Java, C, C++, C#, Objective-C, PHP, VB, Python, Pearl, Ruby, Javascript and the like.

In one embodiment, the NMF, k-means, and/or topology proximity algorithms are optionally repeated. The repeating can be performed by varying k from the previously performed common steps in the signalizer engine 120, and optionally along with the SVD decomposition.

Optionally, generated clusters are tested against a quality function supplied by the system 10 which evaluates a cluster's uniformity. In one embodiment, the system 10 selects a best set clusters against the quality clusters.

As a non-limiting example, clusters are examiner against a customer supplied configuration database for each source of an event. As a non-limiting example, the examining can be performed to determine: a type of device; impacted users; relevant support experts, and the like, FIG. 12.

Example 1

As a non-limiting example, the NMF algorithm can be executed as follows:

Let Mij be an x p non-negative matrix, (i.e., with M>0, and k>0 an integer). Non-negative Matrix Factorization (NMF) consists in finding an approximation X=WH(AB),  (1)

where W, H are n k and k p non-negative matrices, respectively. In practice, the factorization rank r is often chosen such that r<<min(n, p) but is determined.

The main approach to NMF is to estimate matrices W and H as a local minimum:

M=A B

A, B seed randomly tentatively adjusts A, B until the Frobenius distance

∥M−A B∥ is minimized

where

D is a loss function that measures the quality of the approximation. Common loss functions are based on either the Frobenius distance or the Kullback-Leibler divergence.

R is an optional regularization function, defined to enforce desirable properties on matrices W and H, such as smoothness or sparsity.

Example 2

As a non-limiting example, a k-means algorithm is used as follows:

Given a set of event vectors (x₁, x₂, . . . , x_(n)), where each observation is a d-dimensional real vector, k-means clustering aims to partition the n observations into k sets (k≤n) S={S₁, S₂, . . . , S_(k)} so as to minimize the within-cluster sum of squares (WCSS):

$\underset{S}{argmin}{\sum\limits_{i = 1}^{k}{\sum\limits_{x_{j} \in S_{i}}^{\;}{{x_{j} - \mu_{i}}}^{2}}}$

where μ_(i) is the mean of points in S_(i).

FIG. 14 is an example process that may be implemented using the system shown in FIG. 13. Initially, at step 454, in an example embodiment a dashboard design user may build a dashboard using a dashboard building software. The dashboard design user may configure the dashboard during design time. In an example embodiment, design time may include the design user configuring the dashboard layout and exposing a related data range. The dashboard design system 412 may be used to create a dashboard layout. Building the dashboard includes placing components on the canvas and configuring the properties associated with those components. As discussed above, the components may be among other components, a chart or graph. At step 456, the dashboard design user may determine and specify using a graphical user interface the data ranges for the dashboard. After creating the dashboard, at step 458, the dashboard may be exported automatically or by input from the dashboard design user to a SWF file format. Steps 454, 456 and 458 may be performed by the dashboard design user using the dashboard configuration system 412. This is then communicated to a client community system at steps 460, 462 and 464.

A business user may perform the other steps of FIG. 15 by using the display computer system 414. In an example embodiment, the business user's steps may be performed during runtime. In this embodiment, runtime includes displaying of the dashboard in a business application using data from business application data sources. In another embodiment, the business user may perform the steps described above with regard to the dashboard design user.

At step 460, the business user may open the context viewer system where the business user may select a chart view 498 as shown in FIG. 16. In the chart view tab, the business user may assign the dashboard or SWF® file to a query view by specifying the location of the file. At step 462, the dashboard data ranges that were determined at step 456 may be mapped to query view fields.

In an example embodiment, the data from the data source 436 (or 416) is placed in the mapped location in the dashboard. In another example embodiment, the mapping between application data and graphical interface data may identify which application data may be shown in the reserved placeholder of the dashboard. After mapping the data ranges, at step 464 the dashboard may be displayed in the business application.

In another embodiment, the dashboard may be configured to receive data from the data system 416 after the mapping has occurred or the data may be accessed during runtime.

FIG. 18 is an example software architecture that may be implemented using the system in FIG. 14. The software architecture diagram shown in FIG. 17 shows various software layers, such as, graphic player 466, component Dynamic HTML or Java® Script 468, and Server (Java® or Java® based or other high level programming language based) 470 layers. In particular, the generic adapter 472 may be built with the Flash Island library, which may facilitate the client-side communication between HTML and JavaScript®. The Dynamic HTML 468 may load the generated dashboard in a graphic file, or Flash/SWF representation. The generic adapter 472 may convert the Java® context into structures that match the dashboard's external interface format or the dashboard format. The generic adapter 472 allows the business user to generate a dashboard in a business analytic software using the most updated data from a data source without writing any customized software. The generic adapter 472 may load dashboard data ranges and convert the associated data into an XML® string that may be used for further conversion into an ABAP® string, which may be used by the business analytic software.

In another embodiment, FIG. 17, the generic adapter 472 may convert the Flash Island properties into dashboard structures. In an example embodiment, the generic adapter 472 may be used to load external dashboard ranges during the configuration stage, at step 462. In this embodiment, the generic adapter 472 may push application data to the data ranges defined in step 462. In another embodiment, the generic adapter 472 may provide an application programming interface between the graphic player 466 and the server 470. The generic adapter 472 may load dashboard ranges automatically and the dashboard data ranges may be converted into XML strings. The XML string may be converted into Java® or ABAP® code which may be executed by the business application 474, to display a dashboard. The server 470 may include NetWeaver®, ABAP® or Java® language programming and the server may include various systems that are supported in the business software suit, the runtime 382, application 474, database 476 and business intelligence application 478.

In yet another embodiment the functionality of server 470 may be divided between the display computing system 414 and data system 416. In another embodiment, the graphic player 466 may be implemented on the dashboard design system 412. Additionally or alternatively, the functionality of the graphic player 466 may be implemented on the display computing system 414.

FIG. 19 shows a screen display 480 of the dashboard designer that may be used to design a dashboard display according to the system shown in FIG. 12. The dashboard designer may be executed by the dashboard design system 412. The dashboard may be created on the canvas 482. A dashboard design user may place the components from the component panel on the canvas 482. As shown in FIG. 19, the canvas 482 has a bar graph 484 and a pie chart 486 that are displayed in this example dashboard. The dashboard 480 shown in FIG. 19 is using example data from the spreadsheet shown at the bottom of FIG. 19. For example, the labels of the bar graph “Incorrect labeling”, “Wrong component” and “Material defects” are from the spreadsheet shown below. In particular, the cell range from B4 to D5 440 was selected as input into the properties of the bar graph and the pie chart. Next, the data in the bar graph and the pie chart is received from cell range B5 to D5. In order to generate this dashboard the dashboard design user may associate various data fields with particular component properties.

FIG. 18 is a screen display of the dashboard external interface that can permit another software program to access the dashboard controls and display. The external interface connection 488 may allow data from the application system to be passed to a cell range of the dashboard or SWF file, using push technology. During the execution of the dashboard or runtime, data may be pushed or sent from the data source, based on the mapping, to the dashboard. In this embodiment, the data may be transferred in tabular form across an interface. In another embodiment the external interface connection 488 may allow the use of pull technology, where the data is pulled by the context viewer system 438. In another embodiment, during the configuration of the dashboard when the “Generate XC Fields” button is clicked, the defined data ranges will be pulled to the system 450, for example in FIG. 16. The external interface connection 488 may be configured using a definition tab 490, range name 492, range type, range 494 and access type properties. External interface connections allow a dashboard design user to expose selected data ranges relating to the dashboard display. The range name 492 is shown as Labels and the range 494 being assigned, “Table 1!$B$4:$D$4” which is the cell range from B4 to D4. In this example embodiment, the labels from B4 to D4 will be used for mapping the Labels field. After specifying the data range, the dashboard design user may export the dashboard as a file, the file may be executed by various software program including business software.

FIG. 16 is a screen display that allows a user to choose a chart view in order to display a dashboard. In particular, the query view 496 is part of the context viewer application and includes various data types from a business analytics database. If the user chooses to view a chart, the user may select the chart view 498. After a user selects the chart view 498 then the user may be presented with a screen shown in FIG. 20.

FIG. 20 is an example screen display showing the data mapping for the dashboard configuration screen. Screen 510 shows a user interface where the user may select (using a pull down menu) the type of technology 512 the user plans to use for the chart view display. Here, the user may select the type of dashboard file that was created as the technology. Next, the file path 514 of the exported dashboard or SWF file may be specified. After choosing a SWF file, the user may select the “Upload file to repository” button in order to save a graphic file (SWF file) in the system 138. After selecting button “Generate XC Fields”, may be the name of the dashboard external data ranges (e.g. “Damages” and “Labels” in FIG. 18). In the mapping shown in FIG. 18, the user may enter or browse for the name of data source (Query ID). For example, the Query ID shown in this example is “ZOK_QN”. This entry is mapped against the data source that may be stored in the application data 146. The user may search for the Query Field ID, which is a specific field of data source Query ID (e.g. field “CODE TEXT” of Query ID “ZOK_QN” in the provided example). Creating this mapping allows the dashboard to utilize the data in the application data 446 or 430. As can be appreciated that programming in a textual or visual manner is not required and the user may create the dashboard, export the dashboard, map the fields and display the dashboard as shown in FIG. 21 using a graphical user interface that responds to a pointing device (e.g. mouse, pen or display device that is sensitive to touch or ocular movement).

FIG. 21 is an example screen display showing the graphical display of the data using the dashboard configuration from FIGS. 19 and 20. FIG. 21 shows a dashboard 516 that includes the bar graph 518 and pie chart 520. The labels and the value data in the bar and the pie charts 518 and 520 are from the business software and are different than the data used in FIG. 19. Therefore, the user can create a display of a dashboard in another application by using an external connection that may expose data fields to permit the visualization of any type of data.

The embodiments refer to a dashboard that may be a web-based or other technology based display on which real time data is collated, processed and displayed from multiple data sources that belong to one or more businesses.

The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below.

A touch screen has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen and the display controller (along with any associated modules and/or sets of instructions in memory) detect contact (and any movement or breaking of the contact) on the touch screen and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen and the user corresponds to a finger of the user.

The touch screen may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen and the display controller may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen.

A touch-sensitive display in some embodiments of the touch screen may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in their entirety. However, a touch screen displays visual output from the portable mobile or computing device, whereas touch sensitive tablets do not provide visual output.

A touch-sensitive display in some embodiments of the touch screen may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 12, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

The touch screen may have a resolution in excess of 1000 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 1060 dpi. The user may make contact with the touch screen using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, the mobile or computing device may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen or an extension of the touch-sensitive surface formed by the touch screen.

In some embodiments, the mobile or computing device may include a physical or virtual click wheel as an input control device. A user may navigate among and interact with one or more graphical objects (henceforth referred to as icons) displayed in the touch screen by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller as well as one or more of the modules and/or sets of instructions in memory. For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen and the display controller, respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen.

The mobile or computing device also includes a power system for powering the various components. The power system may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

The mobile or computing device may also include one or more sensors, including not limited to optical sensors. FIG. 30 illustrates how an optical sensor coupled to an optical sensor controller in I/O subsystem. The optical sensor may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module 58 (also called a camera module); the optical sensor may capture still images or video. In some embodiments, an optical sensor is located on the back of the mobile or computing device, opposite the touch screen display on the front of the device, so that the touch screen display may be used as a viewfinder for either still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

The mobile or computing device may also include one or more proximity sensors. In one embodiment, the proximity sensor is coupled to the peripherals interface. Alternately, the proximity sensor may be coupled to an input controller in the I/O subsystem. The proximity sensor may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 11/240,788, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 13/096,386, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 13/096,386, “Automated Response To And Sensing Of User Activity In Portable Devices,” filed Oct. 24, 2006; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables the touch screen when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call). In some embodiments, the proximity sensor keeps the screen off when the device is in the user's pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state.

In some embodiments, the software components stored in memory may include an operating system, a communication module (or set of instructions), a contact/motion module (or set of instructions), a graphics module (or set of instructions), a text input module (or set of instructions), a Global Positioning System (GPS) module (or set of instructions), and applications (or set of instructions).

The operating system (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

The communication module facilitates communication with other devices over one or more external ports and also includes various software components for handling data received by the Network Systems circuitry and/or the external port. The external port (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Computer, Inc.) devices.

The contact/motion module may detect contact with the touch screen (in conjunction with the display controller) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred, determining if there is movement of the contact and tracking the movement across the touch screen, and determining if the contact has been broken (i.e., if the contact has ceased). Determining movement of the point of contact may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module and the display controller also detect contact on a touchpad. In some embodiments, the contact/motion module and the controller detects contact on a click wheel.

Examples of other applications that may be stored in memory include other word processing applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

In conjunction with touch screen, display controller, contact module, graphics module, and text input module, a contacts module may be used to manage an address book or contact list, including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone, video conference, e-mail, or IM; and so forth.

In one embodiment a feedback signalizer functor is provided that is a signalizing event analyzer which responds to user interactions with already formed situations. It then learns how to replicate the same situation when new alerts reoccur, or, creates similar situations. In one embodiment the feedback signalizer functor is a supervised machine learning approach to train a signalizer functor to reproduce a situation at varying degrees of precision. As a non-limiting example, this is accomplished by the use of neural networks, in particular a feed forward neural net with the standard configuration of an input layer, configurable hidden layers. This can be considered as deep learning with a single output layer. In one embodiment the use case being addressed by the feedback signalizer functor is to respond to a configurable set of queues to learn and unlearn situations. In one embodiment the feedback signalizer functor is configured to run in farmd.

In one embodiment the feedback signalizer functor listens on the sig journal topic for audited actions on a situation. These actions are collected together into a set of collections of actions, configurable in two parameters: learn_queues and unlearn_queues. As a non-limiting example the following example configuration defines the actions for learn_queues and unlearn_queues:

learn_queues

:[“manual_create”,“merge_create”,“split_create”,“annotated”,“diagnosed”,“closed”,“refin

ed”],

manual_create, the creation of a situation where alerts are brought together in a situation.

merge_create is the creation of a new situation by merging two situations. The learn_queue is on the created situation, not on the two situations that are merged together.

split_create is when you create a new situation by splitting an existing situation, and it is the created situations that are learnt.

annotated is any addition to either a discussion thread or comment, or, the setting of a situation description.

diagnosed indicates a tool has run.

closed relates to whether a situation is closed or resolved.

refined is when alerts are added to or removed alerts from a situation.

unlearn_queues: [“split”],

If this action is taken on a given situation, the neural net, which is created by the learn_queues for the situation is discarded. Any action can be either a learn queue or an unlearn queue.

In one embodiment as part of the feedback signalizer functor a small Java library, neural, exists to encapsulate the neural network. The neural network takes an alert as its input. When a situation is learned, the collection of alerts in that situation is presented to the neural network, which then learns the contents of the situation. In one embodiment the neural network can be configured by selecting any attribute of an alert as shown in the following example configuration:

inputs: [“rsource”,“description”,“severity”,“manager”],

In one embodiment if the element of an alert is not a string, it is converted to a string for consideration in the neural network. In one embodiment the neural network is set up to have an input node for each attribute of an alert. In one embodiment a brain configuration section is used to set up the precise characteristics of the neural network that is used to learn the situation. The following is a non-limiting example of how this can be achieved:

neurons: 7,

layers: 2,

learning_rate: 0.1,

activation_func: “Hyperbolic”,

epochs: 500,

precision: 0.92,

exact_match: false

where:

neurons provide the number of neuron's in the hidden layer. The neural network created by neurons with a value of 7 is shown in figure one.

Epochs, precision and exact_match relate to the number of times a network is trained which is the process of presenting the alerts and then back propagating and adjusting the network configuration to achieve 1.0 and −1.0 as the output layer. epochs is the maximum number of iterations that you will back propagate against a single alert to try and achieve the stated precision. In the embodiment above it is 0.92. As a non-limiting example this would be trained if, presenting an alert to the neural network gave a value of 0.92 on the True and −0.92 on the False. It will iterate until completed, and only terminate the iteration on meeting the error goal, or, exceeding the number of epochs or iteration steps. Exact match parameter is a technical override to the neural network meaning that an alert, which is not used for training, does not provide a positive value for inclusion. In this embodiment because it does not provide a positive value it is clustered. A perfect recall of all the alerts is not achieved. As a non-limiting example, exact_match can provide 100% precision and it can also have less than 100% recall.

Precision is the number of true positives divided by the total number of true positives and false positives. As a non-limiting example when there are nine alerts in the situation that were part of the training, and one alert is not part of the training, the precision is 0.9 (9 dived by (9+1). The number of alerts divided by the number of alerts that should have received in the situation. As a non-limiting example, when it is trained on five alerts and four alerts are received in the situation, the recall is 80% or 0.8.

Learning Rate is key configurations in the training. In this example the learning rate is set at 0.1, and controls how fast the neural network converges on training

An activation_function can be “Sigmoid”, “Hyperbolic” or “Sine” and is not case sensitive. It changes the function used to propagate the value of a neuron to the next layer, by choosing between functions 2, 3 and 4 in the equation below.

In one embodiment if an alert is a member of a situation the neural network takes the alert input for the alert and it is passed through the neural network. As a non-limiting example in classic back propagation training the value of the True output node is optimized to 1.0 and the false output node is −1.0.

FIG. 25 illustrates one embodiment of a network, which as a non-limiting example is a neural network 310. As a non-limiting example every input layer is connected to every neuron on a first hidden layer. Every neuron on a hidden layer is connected to neurons on the next hidden layer, and every neuron on the last layer is connected to both True and False. The connections are a function that takes the numerical value submitted to the neuron and converts it into a value that it propagates onto the next neuron up the layer as follows:

$\begin{matrix} {{{output}({neuron})} = {\sum\limits_{inputs}{w_{i} \times {input}_{i}}}} & (1) \\ {{f(x)} = {1.0 - \frac{1}{1 - {\exp\left( {- {{output}({neuron})}} \right)}}}} & (2) \\ {{f(x)} = {\tan\;{h\left( {{output}({neuron})} \right)}}} & (3) \\ {{f(x)} = {\sin\left( {{output}({neuron})} \right)}} & (4) \end{matrix}$

In one embodiment The value of the neuron is equal to the sum of a weight factor times the input value from the (ith) input node, or, proceeding layer input node equals the value of the neuron. This value is passed to a function that propagates up to the next layer in the neural net.

As a non-limiting example for the activation function, activation_func, there can be three choices: Sigmoid, a standard function that is one minus the exponential of the value of the neuron; Hyperbolic, that uses the hyperbolic tangent, or, tan h of the value, which passes it on, and, Sine that uses a trigonometric sin of the value. A slight technicality is that all the neural nets are symmetric as opposed to asymmetric.

The Sigmoid function can sometimes tend to blur values and can be less precise than the other two activation functions. The Hyperbolic function is more likely to resolve similar alerts, and Sine works better with random data. In one embodiment if the alerts in a situation that is in the process of learning the alerts have little similarity, the Sine function produces better results when recalling that situation, but is less precise. The Sigmoid function produces better precision but has a poorer recall. In one embodiment a back propagation is standard back propagation and the learning rate is the small positive constant used to perform the gradient descent method of solving for the weights in Equation 1. In the FIG. 20 embodiment, with four input nodes, two layers of seven, and two output nodes, there are 91 interconnections between the neurons, ((7*7) nodes+(2*7) nodes+(4*7) nodes)=91. In this embodiment there are 91 weights that characterize the state of the neural network. This can be considered as a form of training by calculating 91 floating point numbers. In this embodiment a unique signature of 91 floating-point numbers are respected as an arbitrary collection of alerts that for training.

As illustrated in FIG. 26 in one embodiment a floating point unit (FPU) 320 performs floating point calculations. In one embodiment floating point arithmetic logic instructions are retrieved from memory of system 10 and or 310 that are then stored in a system 10 and or 310 memory. In one embodiment a BEEFY FPU 320 is used.

In one embodiment the FPU 320 is included in a processor of the system 10 and or 310. In one embodiment the FPU 320 is a stand-alone unit apart for a processor of the system 10 and or 310. In one embodiment the FPU 320 executes floating point arithmetic logic instructions by retrieving them from a memory of the system 10 and or 310. In one embodiment the FPU 320 executes floating point arithmetic logic instructions by retrieving them from a memory of the system 10 and or 310 that are then stored in one or more system 10 and or 310 memory.

In one embodiment the FPU 320 includes one or more of a: floating point adder, multiplier and comparator. As a non-limiting example the FPU 320 performs one or more of: exponent subtraction; subtraction of the exponents to form an absolute difference IE_a−E_bl=d; alignment; significand addition; addition or subtraction according to an effective operation that is a function of an opcode and the signs of operands; conversion that converts a significand result, when negative, to a signmagnitude representation; leading-one detection; normalization; and rounding.

In one embodiment a control unit of a processor carries out stored program instructions relative to the FPU 320. In one embodiment the control unit communicates with the ALU and memory. In one embodiment input signals are propagated through the FPU 320 and a resulting performed operation is a FPU 320 output. In one embodiment the FPU 320 output includes a data word and status information of the event. In one embodiment the status information is a rating of a significance of the event.

In one embodiment the input into the neural network is a conversion of a string into a floating-point number because a value between +1.0 and −1.0 is needed at the output layer. In one embodiment this is achieved by using a version of the standard simhash algorithm that is used to convert a string into a floating-point number and then normalize. Simhash is used where similar items are hashed to similar hash values that is the bitwise hamming distance between hash values.

Example 3

irb(main):003:0>p1.simhash

⇒ 851459198

00110010110000000011110001111110

irb(main):004:0>p2.simhash

⇒ 847263864

00110010100000000011100001111000

irb(main):002:0>p3.simhash

⇒ 984968088

00111010101101010110101110011000

In the preceding the hamming distance of the similar items (p1,p2)=4

whereas (p1,p3)=16 and (p2,p3)=12

The simhash of a phrase is calculated as follow.

pick a hashsize, let's say 32 bits

let V=[0]*32 # (i.e. 32 zeros)

break the phrase up into features

irb(main):003:0>‘the cat sat on the mat’. shingles

⇒ #<Set: {“th”, “he”, “e”, “c”, “ca”, “at”, “t”,

“s”, “sa”, “o”, “on”, “n”, “t”, “m”, “ma”}>

hash each feature using a normal 32-bit hash algorithm

“th”.hash=−502157718

“he”.hash=−369049682

for each hash if biti of hash is set then add 1 to V[i]

if biti of hash is not set then take 1 from V[i]

simhash biti is 1 if V[i]>0 and 0 otherwise simhash is useful because if the simhash bitwise hamming distance of two phrases is low then their jaccard coefficient is high.

As a non-limiting example the simhash function calculates a 64 bit integer for a string, which is then normalized, so, the value is between 1.0 and −1.0 and created by dividing the smiths value by the max value of a signed long integer. The simhash function is designed so that lexicographically similar strings have similar simhash values. The simhash algorithm, takes the string, breaks it into individual and pairs of characters, and, then calculates for each of those 2n−1 substrings, an md5 hash for each of the components before going through a process of progressive XOR'ing of the md5 hashes together. This culminates in an array that is used to collapse down into an integer by bit setting.

In one embodiment test and real world data produce good results so that similar strings such as “server6” and “server7” give similar simhash values. The neural network provides reliable results against both artificial and real world data.

As a non-limiting example a standard configuration can be as follows:

name: “Feedback”,

classname: “CFeedback”,

run_on_startup: false,

process_output_of: “AlertBuilder,

membership_limit: 1,

scale_by_severity: false,

entropy_threshold: 0.0,

single_matching: true,

activation_func: “Hyperbolic”

In one embodiment the standard configuration is back-ended to an alert builder. It can run in both standalone and in chained mode as it listens on the journal function and retrieves its own data from the database.

In one embodiment of the present invention, a user interface 22 is provided that reduces the number of actions the users and makes it more minimal.

As a non-limiting example, incident management is managing problem notifications or events that arise on large computing, application and networking infrastructures. A grouping of these is a “situation” which represents a point in time when one or more related events occurred. In one embodiment it can be composed of a plurality of events.

As a non-limiting example a “situation” is a collection of one or more events and alerts representative of a problem in a managed infrastructure. A grouping of these is a “situation” which represents a point in time when one or more related events occurred. In one embodiment it can be composed of a plurality of events.

In one embodiment machine learning is utilized to educate the system. Over a course of time the system learns from prior situations and can discard things that are not relevant and assists in focusing on the actual things one is looking at in a situation.

In one embodiment a Summary view is provided that provides a high level view of service outages, as illustrated in FIG. 27. This allows one to dive down into situations that have been generated for those services.

In one embodiment the interface allows a high level view of multiple situations. Situations can be viewed in different configurations, including but not limited to: 1) a tabular list view where situations can be ordered by different parameters including but not limited to creation date, moderator, definition or other, FIG. 28. A “Kanban” or workflow view where situations can be arranged and ordered according to their state in a workflow process, FIG. 29.

In one embodiment a filtering mechanism is available to reduce and narrow the number of situations displayed based on desired attributes.

In one embodiment when a situation is generated by the system, a “situation room” is created to contain the situation. A situation is opened and presented in a situation room. The situation room is a collection of all relevant events and alerts that generated the situation, links and references to people and teams assigned to resolve the situation, their chat conversations and other information and tools needed for situation resolution, as well as post-situation analysis and forensics.

In one embodiment the situation room contains an overview section with a “start here” page to help guide the user through the process of situation resolution. This offers up “things to start with”, suggestions, information and tools that can help inexperienced users better understand how to resolve situations. As users become more experienced they may choose to turn off the start here page, FIG. 30.

In one embodiment the situation room contains a “feed” view that displays all activity in the situation's life cycle including machine-generated and user activities.

In one embodiment users can create “posts” in the activity view by entering text or uploading files into an entry field. The content users enter is visible to all users of that particular situation room. Any user can comment on a post and chat conversations with other members involved with a situation can be conducted.

In one embodiment the entry field also accepts “Chat Ops” commands, and users can affect the state of a situation by entering machine-recognized commands including but not limited to entering commands that resolve the situation, or close and archive the situation, FIG. 31.

In one embodiment the team or group rooms exist that are organized around specific teams or functions. As non-limiting examples the team or group room can contain one or more team members and may be organized around existing functional teams within an organization, including but not limited to: network management team room, application performance team room, and the like.

Situations can be linked to team rooms and a situation can be linked to multiple team rooms at the same time.

As a non-limiting example a team room differs from a situation room in that situation rooms exist for a short term and are archived when resolved, while team rooms exist and are used for a greater duration and may be semi-permanent.

As a non-limiting example a team room contains a “feed” view of system and user activity. Members of the room can create posts that other members will see in the feed when they visit the room. When users create a post they can mark it as 1) a question or 2) a tip to solve a problem or 3) a simple text statement. This provides a method for classifying different types of posts and enables organization, search and filtering for specific posts.

As a non-limiting example the activity feed can also include system generated events such as recurring calendar events and system maintenance announcements (e.g. “The directory service will be offline tonight from 11:00 PM . . . .”), FIG. 32.

Alerts have multiple parameters which at the simplest level can be broken into numeric

In one embodiment system 10 is given events, which can be alerts that can include any number of different parameters. Events include one or more parameters, also known as subjects that can include attributes. In one embodiment an event includes an instance of one or more parameters that are examined, analyzed and the like. As a non-limiting example features, situations and like are all parameters. A feature is a numerical value of a parameter, and a parameter vector, hereafter “feature vector” is a concatenation of all of the parameters, e.g., features for an individual event. For purposes of the present invention a manager is an attribute of an event. The values of a manager can change from one organization to another.

In order to represent an event for use in a machine learning context each parameter needs to be converted into a numerical representation. In one embodiment this is achieved by creating a “feature vector” for each event. Each parameter of the event is processed in some way. In one embodiment each parameter is represented by one or more columns, of a table, in the final feature vector.

Events can include both numeric and non-numerical and text parameters. In one embodiment system 10 receives the events as they are received. In one embodiment system 10 breaks the parameters that are non-numerical. An event can have some fields that are nested values. The nested values are lists and can be nested name-value pairs. They all decompose into text or numeric values and the text is converted as more fully described hereafter.

In order to represent an event for use in a machine learning context each parameter, feature vectors are created in order to do the conversion of non-numerical and text parameters. Each parameter of the event is processed in some way and is represented by one or more columns in the final feature vector.

Each parameter, whether text or numeric, can represent a “real” value e.g. a number where there is a natural ordering or scale or a textual description. Alternatively, the parameter may represent some sort of categorical value/enumeration. Time based parameters (features) are also possible as are derived/ensemble parameters such as arrival order. These are parameters not contained within the event itself but can be derived from the entire set of events

In one embodiment, illustrated in FIG. 33, a column represents a time and can be sorted in any time desired. In one embodiment system 10 assigns an importance of a parameter based on time. As non-limiting examples, time can be handled a number of different ways including but not limited to as: an absolute value; an assembled parameter, in order of arrival, e.g., the first, second, third to arrive; ordered by time, severity and the like. In this manner an arrival order can be based on any parameter and not only by severity.

As a non-limiting example, and referring to FIG. 34, a slide demonstrates an example of parameters/features of a subject. Also illustrated is how system 10 deals with events relating to that subject. As a non-limiting example a parameter/subject features table can have four attributes of the subject which some numeric and others are text. System 10 turns the non-numerical parameters into numbers.

In one embodiment if parameters are numeric then they are all entered without further conversion action by system 10. If they are not numerical, a yes/no answer is turned into a number, where the yes become 1's and the no's become 0.

In one embodiment a parameters can have multiple attributes. System 10 provides for different categories as well as the creation of as many columns as there are categories. Machine learning algorithms, including but not limited to Boolean, are utilized. In one embodiment a Boolean value is assigned to a column.

In one embodiment severity is a number of a feature vector and occupies one column of the feature vector.

As a non-limiting example system 10 can use shingles which are multiple letter segments of a word. In one embodiment system 10 does this for all host names. As a non-limiting example system 10 can receive a number of shingles. As a non-limiting example the word “switch” has six shingles in it.

As a non-limiting example a parameter can include a plurality of words. As a non-limiting example there can be three host names. In this embodiment the number of columns required is the number of unique shingles across all host names.

In one embodiment system 10 looks at individual phrases rather than shingles. Again in this embodiment system 10 is dealing with words and phrases that have meaning and need to be converted to numerical values. The feature vector needs as many columns as there are unique words.

In one embodiment manager changes from organization to organization and it is the term provided by an organization. As a non-limiting example manger can be the name of the computer system/process that generated the event. Each organization can use different terms for any event/alert. System 10 can include a plurality of columns in the feature vector. As a non-limiting example these can include severity, host name, and the like. In one embodiment the columns represent the description, and columns can also represent the manager.

In one embodiment when system 10 examines text parameters system 10 goes through tokenization to convert sentences into words and can get rid of stop words. In one embodiment stemming is used to de-pluralize words.

System 10 can utilize a variety of different ways to deal with text based parameters, including but not limited to: shingling, tokenization, and the like, and a variety of ways to handle non-numeric parameters. System 10 can mix and match these. System 10 can apply any text based parameter extraction methods to any text based parameter. System 10 deals with attributes, text or numeric, by a plurality of methods of handling different types of parameters, and can use any of those handling techniques. In one embodiment system 10 mixes and matches any of the preceding. In one embodiment for parameters that represent categories, a number or text based fields can be treated as a category. This is another way of doing the mixing and matching. System 10 can treat the same parameter in a plurality of ways in the same model.

As a non-limiting example, severity can be treated as a numerical value of from 0-7, with 0 being the lowest value. There is a natural order to this and represents the significance of a parameter. System 10 can treat it as a number as well as a categorical parameter. System 10 can constrain variable length shingle or word lists to a fixed size feature vector. As a non-limiting example this allows system 10 to apply a system parameter, or solution to an event from organization A to organization B. In this regard, system 10 can use what has been done for one organization to other organizations. As a non-limiting example a category at a high level is what does this event representation. In one embodiment system 10 can proceed further into the parameters of the event. As a non-limiting example some parameters represent categories as well. For example, manager can be a category. In one embodiment of an event, a categorical parameter is different values represent un-connected attributes. The individual components are the parameters.

Problems can be present with incomplete data. As non-limiting examples, this can be caused by: (i) there can be many connected components that have a small size; (ii) many unknown nodes can be in an alert's name.

In one embodiment the topology can be inferred in response to a time series. This can be achieved when alerts are only spread to adjacent node and the network remains stationary.

In one embodiment system 10 predicts the topology of a network in response to a convolution of sparse time series.

FIG. 35 illustrates one embodiment of a time series example.

FIG. 36 illustrates one example of a classic cross-correlation that includes a time series f and g, a mean off, a mean of g, a standard deviation of f and a standard deviation of g.

As illustrated in FIG. 37, thresholding can be used to infer an edge, with a neural network structure inference from its time series.

Referring to FIG. 38, a time series can be too sparse. The mean and variance may not make much sense.

Convolution is computationally much faster. One embodiment of a convolution example is illustrated in FIG. 39, with a time series X, a time series Y and a convolution product of X and Y.

In one embodiment, the smaller the delay between two peaks of two different series the more likely they are caused by the same phenomenon. Additionally, the more peaks of two different series separated by the same delays it is more likely that they are caused by the same phenomenon.

Referring to FIG. 40, in one embodiment a new measure is provided where the number of peaks with a convolution product for delays between and T.

As a non-limiting example the number of peaks within the convolution product for delays between 0 and T is illustrated.

In one embodiment, illustrated in FIG. 41, a Poisson process is utilized where X is a Poisson process of intensity lambda. The probability of k points exists in [0;T].

For a node emitting n alerts, P(X=n) is maximized by choosing: λ=n/T. A theoretical model of the Poisson process is as follows: X Poisson process in [0;T] of intensity nx/T; and Y Poisson process in [0;T] of intensity ny/T.

In one embodiment the nx, ny and T parameters are extracted as follows:

$\begin{matrix} {{R_{X,Y}(\tau)} = {\sum\limits_{{\delta\; t} = 0}^{\tau}{{\mathbb{E}}\left( {{X\left( {{.{+ \delta}}\; t} \right)}{Y\left( . \right)}} \right)}}} \\ {= {\sum\limits_{{\delta\; t} = 0}^{\tau}{{{\mathbb{E}}\left( {X\left( . \right)} \right)}{{\mathbb{E}}\left( {Y\left( . \right)} \right)}}}} \\ {= \frac{\tau\; n_{X}n_{Y}}{T^{2}}} \end{matrix}$

As illustrated in FIG. 42, in one embodiment the evolution of the number of peaks within f*g as a function of nf.ng and τ are considered.

As a non-limiting example the exponential division of the space of nf.ng is typically always the same number of pairs (f,g) in each category.(e.g. {100; 100.5; . . . ; 1010}).

As a non-limiting example for the exponential division of the T intervals the first instants are more important than the following one. (e.g. {100; 100.1; . . . ; 102.8≈10 minutes}).

Referring now to FIG. 43, in one embodiment of the role of NF.NG is illustrated.

In another embodiment, as illustrated in FIG. 44, the role of NF.NG is illustrated. FIG. 45 illustrates another embodiment of the role of NF.NG. FIG. 46 illustrates the role of Tau.

In one embodiment of the present invention the following steps are taken for each pair of nodes: computation of the convolution; number of peaks within the convolution as a function of the delay; comparison to the average behavior of pair of nodes that emits the same number of alerts nf.ng=>score assignation; and thresholding and keep the only pair of nodes that have a score greater than a threshold.

FIG. 47 illustrates one embodiment of convolution computation. Step 2 is illustrated in FIG. 48. Step 3, score calculation, is illustrated in FIG. 49. Step 4, thresholding, is illustrated in FIG. 50.

In one embodiment an assumption is made that Alerts are caused by dysfunctional nodes that do not emit alerts=>nodes at distance 2. However, there is a limitation as illustrated in FIG. 51. As a non-limiting example there are many more nodes at a distance 4/6/8 than at distance 2.

In one embodiment, illustrated in FIG. 52, a low predictive power is utilized. As a non-limiting example, a threshold can be fixed to 3. An estimation is made of the number of pairs that have a surprise higher than 3 as a function of distance.

FIGS. 53 and 54 illustrate an embodiment of a score threshold verses a relative percentage and distance verses a number of pairs. As a non-limiting example an evolution of a relative percentage of pair nodes at a selected distances, including but not limited to 2 and 1, is detected against a pair of nodes at a selected distance, which can be 4, as a function of the threshold.

In one embodiment the following are provided: (i) alerts are only spread to adjacent nodes; (ii) alerts are caused by dysfunctional nodes that do not emit alerts; and (iii) the true topology coincides with the end of the recording.

FIG. 55 illustrates one embodiment of a taxonomy that can be used with a plurality of nodes. As a non-limiting example, the nodes can include, but are not limited to: UCSM; hosts, parents; children and storage.

In one embodiment, illustrated in FIG. 56, components of the managed infrastructure are connected using sub-graphs where any two nodes are connected to each other by a path.

In one embodiment a giant component is provided. FIG. 57 illustrates a histogram of a degree distribution of the gigantic component.

As a non-limiting example, in one embodiment there are 2,946,413 alerts over approximately 5 months, 53,558 nodes, with an average of 100 alerts per node. This provides a spare time series. FIG. 58 illustrates, as a non-limiting example, a distribution of the number of alerts per node.

FIG. 59 illustrates one embodiment of an optimal window size considering a different duration of the recording considered ([0;T], [T/2;T], [3T/4;T]; . . . :[1023T/1024;T]), with true positive/true positive plus false negative. As illustrated a percentage of node pairs are among those that are possible to detect that are detected as fa function of the size of a consider time frame.

FIG. 60 illustrates one embodiment of an optimal window size where a different duration of the recording is considered ([0;T], [T/2;T], [3T/4;T]; . . . ; [1023T/1024;T]). Referring to FIG. 61, the percentage of pair of nodes are illustrated that are possible to detect, when they are at a distance of 1 or 2 of and their cross-correlation has at least one peak, as a function of the size of the consider time frame.

In one embodiment there is a division of the recording. As a non-limiting example, a choice of windows with a duration 105 seconds, for computational reasons, can include the following: first a division of the recording is made in consecutive windows of 105 seconds (e.g. w1=[0; 105], w2=[105; 2.105], . . . , w127=[126.105; T]); and then a computation of the score for each pair of nodes for each window is completed.

In one embodiment of a validation the following assumptions are made: there is a true topology at the end of the recording; and the topology is slow to change. For the data the following are considered: each pair of nodes relative to a window is scored; and a topology at the end of the recording is used. A requirements for validation includes the following: the later a pair has a high score leads to the more likely it is still true at the end, the more likely it is to represent a true edge; and the more often a pair has a high score the more likely it is to stable over the whole recording, as well as the more likely it represents a true edge even if not present at the end, and alerts do not necessarily exist.

FIG. 62 illustrates one embodiment of a first requirement. As shown the percent of pairs correctly detected among those that are detected is illustrated in red, and the percent of pair that can be a function of the window number are shown in blue. Pairs are selected if they have at least one score, which as a non-limiting example can be greater than 5, and close the window number, as a non-limiting example can be a distance of less than 2.

As illustrated in FIG. 63 a tradeoff is made relative to the number of pairs correctly detected, as a non-limiting example at a distance of 1 or 2, and as a function of the window number. Pairs are selected if they have at least one high score after the window number.

FIG. 64 illustrates one embodiment of a second requirement where: the percentage of pairs correctly detected, i.e. that are at distance 1 or 2, and also as a function of the number of times they are detected is required; and the pairs are selected if they have at least x high scores, as a non-limiting example greater than 5.

FIG. 65 illustrates one embodiment of threshold testing where: the percentage of pairs correctly detected, i.e. that are at distance 1 or 2, and also as a function of the number of times they are detected is required; and the pairs are selected if they have at least one score higher than the threshold.

It is not intended to be exhaustive or to limit the claimed subject matter to the precise forms disclosed. Many modifications and variations will be apparent to the practitioner skilled in the art. Particularly, while the concept “component” is used in the embodiments of the systems and methods described above, it will be evident that such concept can be interchangeably used with equivalent concepts such as, class, method, type, interface, module, object model, and other suitable concepts.

What is claimed is:
 1. An event clustering system, comprising: a managed infrastructure with hardware components; an extraction engine in communication with the managed infrastructure, the extraction engine extracting text components from event messages and convert them into words and subtexts; a signalizer engine that includes one or more of an NMF engine, a k-means clustering engine and a topology proximity engine, the signalizer engine converting at least a portion of the event messages into a sequence of attributes that have text or numerical values indicative of a state of a hardware component and determining if collections of event messages share a common attribute, possessing either identically equal textual values, or values that are similar up to a pre-defined threshold with production of an output of clusters, and in response to production of the clusters one or more physical changes in a managed infrastructure hardware is made.
